使用Docker API啓動容器API

我正在嘗試使用Docker REST API部署容器。我能夠創建一個本地圖像並創建一個容器。然而，在啓動容器時，我收到以下錯誤：使用Docker API啓動容器API

 {"message":"starting container with non-empty request body was deprecated since v1.10 and removed in v1.12"}

爲start請求dockerd日誌是：

 err-code: 400 
    time="2017-06-13T07:33:12.679308012Z" level=debug msg="Calling POST /containers/67cf42e1cb92c754ec00a7ec6e02d22ef5ab2267406d7749a85e983481fc0c03/start" 
    time="2017-06-13T07:33:12.679451206Z" level=debug msg="form data: {\"Binds\":[],\"PublishAllPorts\":true}"

發送空請求體後，我得到以下從dockerd錯誤日誌：

err-code: 404 (no such container - https://docs.docker.com/engine/api/v1.19/#2-endpoints) 
    time="2017-06-13T07:54:16.483161021Z" level=debug msg="Calling POST /containers/dbaabc5f437f/start"

搬運工PS對服務器的輸出是：

$ docker -H=<host-name>:2376 ps -a 
    CONTAINER ID  IMAGE    COMMAND    CREATED    STATUS    PORTS    NAMES

有什麼不清楚的錯誤信息？請求主體必須是空的。 – Henry

對不起，我錯過了發送錯誤我發送空請求正文。修改上面的問題。 –

這裏有幫助：https：//github.com/docker/compose/issues/4039？ –

我沒有意識到，在創建容器時，我應該傳遞要執行的命令。 Dockerfile具有CMD行，但顯然如果必須使用REST API啓動容器，則必須明確傳遞要執行的命令。

不確定這是否是期望的行爲或Docker引擎中的錯誤。

對於配置泊塢窗守護程序端口的更多詳細信息，refer configure-docker-daemon-port

一旦泊塢端口配置，您可以訪問泊塢窗的API在遠程主機。

JSON輸入文件：

API來創建容器：

curl -X POST http://192.168.56.101:6000/containers/create -d @container_create.json --header "Content-Type: application/json" | jq .

我可以重現你已經通過運行下面的命令中規定的問題：

curl -v -d "{\"Binds\":[],\"PublishAllPorts\":true}" --unix-socket /var/run/docker.sock http://localhost/v1.27/containers/0df187bd421a/start 
* Trying /var/run/docker.sock... 
* Connected to localhost (/var/run/docker.sock) port 80 (#0) 
> POST /v1.27/containers/0df187bd421a/start HTTP/1.1 
> Host: localhost 
> User-Agent: curl/7.53.0 
> Accept: */* 
> Content-Length: 35 
> Content-Type: application/x-www-form-urlencoded 
> 
* upload completely sent off: 35 out of 35 bytes 
< HTTP/1.1 400 Bad Request 
< Api-Version: 1.29 
< Content-Type: application/json 
< Docker-Experimental: false 
< Ostype: linux 
< Server: Docker/17.05.0-ce (linux)

< Content-Length: 109 
< 
{"message":"starting container with non-empty request body was deprecated since v1.10 and removed in v1.12"} 
* Connection #0 to host localhost left intact

此錯誤消息是相對簡單的。嘗試啓動容器時，我不應該包含任何內容但空的內容。我可以調整命令發送一個空的身體，我可以開始我的容器：

curl -v -d '' --unix-socket /var/run/docker.sock http://localhost/v1.27/containers/0df187bd421a/start 
* Trying /var/run/docker.sock... 
* Connected to localhost (/var/run/docker.sock) port 80 (#0) 
> POST /v1.27/containers/0df187bd421a/start HTTP/1.1 
> Host: localhost 
> User-Agent: curl/7.53.0 
> Accept: */* 
> Content-Length: 0 
> Content-Type: application/x-www-form-urlencoded 
> 
< HTTP/1.1 204 No Content 
< Api-Version: 1.29 
< Docker-Experimental: false

< Server: Docker/17.05.0-ce (linux) 
< Date: Tue, 13 Jun 2017 15:59:20 GMT 
< 
* Connection #0 to host localhost left intact

這個問題在這個GitHub的問題，還討論：https://github.com/moby/moby/issues/25667

簡短的回答是確保你在容器創建時傳遞適當的配置，然後在調用端點POST /v1.27/containers/<container>/start時傳遞空的主體。

在the rapid dashboard中，您可以應用幾個步驟來啓動並記錄容器。

開始迅速UI後

$ docker run -d --name rapid \ 
    -v /var/run/docker.sock:/var/run/docker.sock \ 
    -p 8080:8080 \ 
    ozlerhakan/rapid

您可以鍵入以下步驟來做到這一點：

POST images/create?fromImage=ubuntu&tag=latest 

POST containers/create?name=mycontainer 
{ 
    "Cmd": [ 
    "date" 
    ], 
    "Entrypoint": "", 
    "Image": "ubuntu" 
} 

POST containers/mycontainer/start 

GET containers/mycontainer/logs?stdout=true&tail=all

所有上面的命令可以被轉換爲有效的捲曲命令，以及：

curl --unix-socket /var/run/docker.sock -XPOST "http:/v1.30/images/create?fromImage=ubuntu&tag=latest" 

curl --unix-socket /var/run/docker.sock -XPOST "http:/v1.30/containers/create?name=mycontainer" -H "Content-Type: application/json" -d' 
{ 
    "Cmd": [ 
    "date" 
    ], 
    "Entrypoint": "", 
    "Image": "ubuntu" 
}' 

curl --unix-socket /var/run/docker.sock -XPOST "http:/v1.30/containers/mycontainer/start" 

GET containers/mycontainer/logs?stdout=true&tail=all 

curl --unix-socket /var/run/docker.sock -XGET "http:/v1.30/containers/mycontainer/logs?stdout=true&tail=all"
